Key findings:
- dorsal talonavicular ligament thickened and hyperintense (red arrowhead) with bony avulsion (red arrow) visible on x-ray and confirmation on CT
- dorsal calcaneocuboid ligament hyperintense and thickened (blue arrowheads), especially the lateral accessory band visible on axial images (light blue arrowheads) also with bony avulsion injuries of the origin (blue arrow) and the distal insertion of the accessory lateral band (light blue arrow)
- the calcaneonavicular component of the bifurcate ligament also hyperintense and thickened (yellow arrowhead) with partial avulsion in the area corresponding to the proximal origin, hardly visible on x-ray and CT (yellow arrows)
- bone marrow oedema-like signal in the talar head (orange star) and sustentaculum tali (yellow star) from impaction injury
- the superomedial (orange arrowheads) medioplantar oblique (light green arrowheads) and inferoplantar longitudinal (dark green arrowhead) components of the spring ligament complex are continuously visible
- the calcaneocuboid component of the bifurcate ligament (yellow arrow) looks irregular and torn
- note: only mild bone marrow oedema-like signal associated with those avulsion injuries
